Yes their first kiss was after Ginny's final quiditch match where Ginny and the rest of the team successfully beat Ravenclaw and won the Quidditch Cup. Harry was not able to play after receving detention from Professor Snape for attacking Malfoy. Once Harry retuned to the common room, GInny ran up to Harry, and he kissed her. He compared it to "several sunlit days" after this moment they dated for the rest of the year until Harry ended the relationship in order to protect Ginny from You-Know-Who. They later reconciled and and got married and had 3 children.
